The XC6124E639MR-G is a precision voltage detection device designed for use in system power supply and battery management systems for automotive, industrial and consumer applications. The device combines high accuracy, wide Input voltage monitoring and extreme flexibility in application. It employs an accuracy of ±0.05%. The XC6124E639MR-G is highly configurable, allowing the user to select the output voltages and hysteresis levels over the entire range. The device is fully programmable and can be tailored to an application’s specific needs.

The XC6124E639MR-G is a supervisory circuit with a flexible high accuracy threshold comparator. This comparator is configured to monitor both negative and positive supply voltages to ensure that they remain within safe operating levels. The comparator also has an on-chip level-shifter, which allows the device to interface with negative supply rails. When the voltage drops below or rises above the programmed level, an output flag is triggered, indicating the out-of-tolerance condition. This flag can be used to assert an external reset signal to ensure that the system does not continue to run if its voltage levels get too far out of tolerance.

The XC6124E639MR-G is well suited for use in systems requiring protection from over/undershoot voltages as well as systems incorporating multiple power supplies. The device offers wide input voltage ranges from 0.7V to 6.0V, and is capable of monitoring voltages up to 65V. The device also features a minimum supply current of 230µA, which allows it to be powered from a single rail source. Additionally, the device is offered in both surface mount and free-standing packages, allowing for preferences in space saving and system mountings.

The XC6124E639MR-G combines precision voltage monitoring with additional features found on higher end microcontroller-based solutions. The device has a Programmable Oscillator and an Update Delay feature, which allows control of the output latch timing both reset and active indicating flags. Moreover, the device’s transparent four-wire serial programming port and DIP switch options enable full software re-programming of voltage setting and hysteresis levels. The programming provided with the device eliminates the need for carrier boards and the need for changing on-board parts with replacements from the factory or end-users.

In conclusion, the XC6124E639MR-G is a precision voltage detection device designed for use in system power supply and battery management systems for automotive, industrial and consumer applications. The device offers wide input voltage ranges, low supply current and a Programmable Oscillator and Update Delay feature, offering more flexibility and accuracy than other microcontroller-based solutions. The device is both cost-effective and space-efficient. It is ideal for use in systems requiring high accuracy and monitoring of negative and positive supply voltages.
